AIR CONDITIONING UNIT AND METHOD OF OPERATING THE SAME

摘要

Disclosed herein is an air conditioning unit and method of operating the same. The air conditioning unit has a power level control unit ( 6 ) for controlling the level of power supplied to a motor ( 2 a) of a compressor. The power level control unit ( 6 ) is comprised of a first supplying unit ( 6 a) for supplying first level power to the compressor motor ( 2 a), and a second supplying unit ( 6 b) for supplying second level power to the compressor motor ( 2 a). If an operation cycle of the compressor corresponds to a loading operation, the power level control unit ( 6 ) supplies first level power for compressing a cooling agent through the first supplying unit ( 6 a). Further, if an operation cycle of the compressor corresponds to an unloading operation, the power level control unit ( 6 ) supplies second level power less than the first level power through the second supplying unit ( 6 b). Therefore, the present invention is advantageous in that it can reduce undesirable power consumption caused by the compressor motor during the unloading operation.
